UART 2 does not support AFC function, because the S3C2410A has no nRTS2 and nCTS2.

0x5000400C
0x5000800C

[0]
These bits must be 0's
0 = Disable
These bits must be 0's
If AFC bit is enabled, this value will be ignored. In this case
the S3C2410A will control nRTS automatically.
If AFC bit is disabled, nRTS must be controlled by software.
0 = 'H' level (Inactivate nRTS)
1 = 'L' level (Activate nRTS)
